In the center of our galaxy is a black hole named Sagittarius A* and it has a mass of approximately 8.6x1036

kg. A 90 kg astronaut that is 1.5 m tall is falling feet first towards this black hole. If their feet are located 765

million meters away from the center of the black hole, what is the difference in the acceleration of gravity

between their head and their feet? What does this imply is happening to them?
